About:
Speex is a patent-free compression format designed especially for speech. It is specialized for voice communications at low bit-rates in the 2-45 kbps range. Possible applications include Voice over IP (VoIP), Internet audio streaming, audio books, and archiving of speech data (e.g. voice mail).

Release focus: Major feature enhancements

Changes:
This release adds support for acoustic echo cancellation with multiple microphones and multiple loudspeakers. It also adds an API for decorrelating loudspeaker signals to improve multi-channel performance. A few bugs were fixed in the echo canceller, jitter buffer, and preprocessor. At this point, the API for 1.2 should be stable and only a few very minor additions are planned.
